Overview
HZAOC GDJW-800C low/high temperature test Chamber is suitable for the adaptability test of electrical, electronic products, components, parts and materials in high and low temperature environment storage, transportation and use, as well as temperature gradual change test, and stress screening test for electronic components. The box adopts the overall structure, the inner side is 1.0mm SUS304B stainless steel plate, the outer side is 1.0mm Cold rolled steel plate spray, and the thermal insulation material is ultra-Glass fine thermal insulation cotton to ensure stable performance.
Features
1. The box adopts double-decked sealing door and ultra-fine Glass thermal insulation cotton, which has good thermal insulation effect
2. The observation window is equipped with multi-layer conductive film tempered hollow Glass and built-in heating wire to prevent frosting
3. The heating system adopts porcelain frame nickel-chromium wire electric heating device, which has small thermal inertia and long service life
4. The refrigeration system adopts French Taikang fully enclosed Compressor and imported parts from many countries
5. Control system with High Accuracy Digital Temperature Controller and Multiple Safety protection
6. The air supply method is the upper air supply and the lower air return, Temperature Uniformity ≤ +/- 2.0 ℃
Principle
The test Chamber achieves temperature control through the heating system and the refrigeration system. The heating system consists of a porcelain frame nickel-chrome wire electric heating device, which controls the PID signal through a solid-state relay; the refrigeration system adopts a French Taikang fully enclosed Compressor and uses R404A environmentally friendly refrigerant. The temperature sensor is placed in a trend, and the Control system adjusts the temperature according to the set parameters to realize high and low temperature environment simulation.
Applications
Electricians, electronic products, components, parts, materials
